首先，AndroidManifest.xml 中添加一个权限：<uses-permission android:name="android.permission.READ_PHONE_STATE"/>

其次，

private static String getIMIEStatus(Context context) {
    TelephonyManager tm = (TelephonyManager) context
            .getSystemService(Context.TELEPHONY_SERVICE);
    String deviceId = tm.getDeviceId();
    return deviceId;
}
